Display screen or portion thereof with animated graphical user interface



FIG. 1 is a front view of a first image in a sequence for a display screen or portion thereof with animated graphical user interface showing our new design; and,

FIG. 2 is the second image thereof.

The appearance of the animated graphical user interface sequentially transitions between the images shown in FIGS. 1 to 2. The process or period in which one image transitions to another forms no part of the claimed design. The broken lines around the Figures show a display screen or portion thereof and form no part of the claimed design, and the broken lines within the Figures show portions of the graphical user interface that form no part of the claimed design. 

CLAIM We claim the ornamental design for a display screen or portion thereof with animated graphical user interface, as shown and described.
